fast a bus can transfer information.
byte — The basic data unit used by your computer. Een
byte is gelijk aan 8 bits.
C
C — Celsius — A temperature measurement scale where
0° is the freezing point and 100° is the boiling point of water.
cache — A special high-speed storage mechanism which
can be either a reserved section of main memory or an
independent high-speed storage device. Het cache-
geheugen vergroot de efficiëntie van processor-
bewerkingen.
L1 cache — Primary cache stored inside the processor.
L2 cache — Secondary cache which can either be external
to the processor or incorporated into the processor
architecture.
carnet — An international customs document that
facilitates temporary imports into foreign countries. Dit

CD. Op een cd-rw kunt u gegevens opnemen, deze wissen
en overschrijven (opnieuw opnemen).
CD-RW drive — A drive that can read CDs and write to
CD-RW (rewritable CDs) and CD-R (recordable CDs)
discs. U kunt meerdere keren naar cd-rw's schrijven, maar
slechts één keer naar cd-r's.
CD-RW/DVD drive — A drive, sometimes referred to as a
combo drive, that can read CDs and DVDs and write to
CD-RW (rewritable CDs) and CD-R (recordable CDs)
discs. U kunt meerdere keren naar cd-rw's schrijven, maar
